With readily available full assemblies and
interchangeable components, Lovejoy's new
line of grid couplings gives you the ability to
avoid lengthy shutdowns. Our grid couplings
combine high-torque, high-horsepower opera-
tion with vibration, shock and misalignment
capabilities not provided by other metallic cou-
pling types. Ten standard model sizes feature
an advanced design with high-tensile alloy grids
that reduce vibration by as much as 30 percent.
Our larger grid couplings meet the demands
of tough applications like crushers, conveyors,
and pulverizers commonly found in aggregate
industries.
Benefits of Lovejoy Grid Couplings:
✔
Interchangeable with industry
standard hubs and grid springs –
all the way up to size 1200!
✔
Clearance fit hubs available in sizes
1020-1090 have two set screws standard
✔
The tooth profile of the grid hub is shot
blasted for added strength and longer life
✔
Puller holes are standard for interference
fit hubs, sizes 1100 through 1200
✔
Cover fasteners are available in either
metric or imperial sizes
✔
Grease packets are included with cover
sets through size 1090
✔
Standard hubs accommodating
Taper-Lock®bushings are standard
Fully Interchangeable

Note: 1. Misalignment ratings pertain to both standard and spacer grid couplings.
The movement of the grid in the hub grooves
accommodates parallel misalignment and still
permits full functioning of the grid-groove
action in damping out shock and vibration.
Under angular misalignment, the grid-groove
design permits a rocking and sliding action of
the grid and hubs without any loss of power
through the resilient grid.
End float is permitted for both driving and
driven members because the grid slides freely
in the grooves.
